So suppose I make a mad flame using Ctrl + L ingame.
And then take screen shots of it while its in action.

Now I don't have the TC to Forge it so I put the Flame Screenies on the forums for sale.
Then if someone buys it they pay for the forging and I make the Flame and send it to them. With a bit of extra TC as well.

Is that how it works?

Because I'm really confused about this flame business.

you could do that. Most people (imo) do not make flames just to sell em. They make em to use em and then eventually they may sell em. But, i warn u. most people will not pay the amount it costs to forge the flame. So it will be really hard to sell. But, if you want, go rite ahead...

You should make AND get the flame before you sell it.
